Wet electric closed-loop control electricity saving method

Abstract

The invention discloses a wet electric closed-loop control electricity saving method. According to the method, on the basis of manual setting of wet electric running parameters, chimney smoke concentration signals are guided into a wet electric power source transformer control system, the output current of a wet electric power source is subjected to programmable control adjustment, and the wet electric consumption is reduced to the maximum degree on the premise that wet electric normal running and the smoke discharging concentration are guaranteed; and guiding of the chimney smoke concentration signals into a wet electric power source control system and programmable control adjustment over the output current of the wet electric power source refer to that the chimney smoke concentration is guided and connected to be displayed to the wet electric control system, and the wet electric running parameters are automatically adjusted according to the chimney smoke concentration. According to the wet electric closed-loop control electricity saving method, an original wet type electric precipitation control procedure is improved, and the wet electric closed-loop control electricity saving method has the beneficial effects that the program structure is simple, achieving is easy, the wet electric consumption can be greatly reduced, the ultra-low emission running economical efficiency and reliability of a coal-fired unit are obviously improved, and obvious functions are achieved for economical and environment-friendly running of the coal-fired unit.

Description

technical field [0001] The invention relates to a wet electricity closed-loop control power saving method, which is mainly used to reduce the power consumption of wet electricity power supply, and belongs to the technical field of wet electricity automatic control system. Background technique [0002] With the ultra-low emission requirements of coal-fired units, most coal-fired units are equipped with wet electrostatic precipitators (referred to as wet electricity). After adding wet electricity, it is bound to increase the corresponding wet electricity power supply and auxiliary water system-related water pumps. Among them, the energy-saving range of wet electricity water pumps Narrow, the main energy-saving direction is to provide high-voltage electric field power for wet electric fields. However, at present, according to the manufacturer's design, the fixed value operation is used to cause high wet power consumption. In order to save energy, it is found through experiment...
